AUTOMATIC coNnnNsAmon-rmvir.

To all whom it may concern Be it known that we, PERCY M. CRooKE'rT,LOUIS J. EHLINGER, and JAMES J PowERs, citizens of the United States,residing, respectively, at Norristown, Conshohocken, and WestConshohocken, in the county of Montgomery and State of Pennsylvania,have invented a new and useful Automatic Condensation-Pump, of which thefollowing is a specification. 1

This invention is an apparatus for automatically disposing of thecondensation resulting from the use of steam as a source of ower.

ne of the objects of the invention is to provide a trap orreceptacle'into which the water of condensation may accumulate, andmeans cooperating with the receptacle to automatically empty it when theaccumulated liquid reaches a predetermined volume. A further object isto providemeans whereby steam pressure may be employed to empty thereceptacle of the accumulated liquid. A further object is to providemeans whereby the weight of 'thewater of condensation is utilizedtocontrol the admission of steam to the receptacle for the purpose ofemptying the latter.

The invention will be hereinafter fullyset forth and particularlypointed out'in the claims;

In the accompanying drawin'gsz- M Figure 1 is anend view illustrating anautomatic condensation pump v constructed in accordance with theinvention. Fig. 2 is a plan view thereof. Fig. 3 is a side view withparts in section, showing the tank in tilted position. Fig. 4 is anenlarged sectional view on the line H Fig. 2. Fig. 5' is an enlargedtransverse sectional view on the line 5-5 Fig.2. Fig. 6 is a detailperspective view illustrating the trunnioned shaft and cam. i

Referring to the drawings, 10 designates a base to which are secured insuitable manner, bearings 11 and 12, which support an oscillatorytrunnion shaft 13. The ends of the shaft extend throughstufling boxeswhich may be of any desired construction, but illustrated as cqnsistmgof spaced apart packing rings 14: and an interposed adjustment spring15, retained in place by a suitable gland 16. l 4

The shaft 18is provided with an enlargement 1'? between its ends, towhich-is re.-

movably secured means of bolts 17, a

pad 18 attached to the'underside of a tank or receptacle -19." Said tankis divided into a reservoir 20, and counter-weight cham-:

ber 21, the latter containing sand or any other weightingmaterialconveniently illustratedat 22. The base 10 is provided withstops '23 and 24: forlimiting the rocking movement of the receptacle 19because of its attachment to the trunnion shaft 13. The bearing 11, isprovided with an opening 25 to receive the end of a supply pipe "'26.'The shaft13 is provided with 27 registering with the opening 25'andforming a continuation of the pipe26, said conduit havinga chamber 28within the enlarged portion 17 of the shaft. The reservoirQO-communicates with the chamber- 28 the pipe 30. For the purposeoffacilitating thein'sertion' and removal of the pipe 80*and for Iinspecting and "cleaning, the re- Ceptac'le is provided'with'an opening31 contiguous to the end of; pipe 30 said openg normally closed by aremovable plug 32.} i

The bearing 12 is provided with an extension in which is formed achamber 35, which communicates with the reservoir 20 through aconduit36formed in theshaft 13, anda discharge pipe 37 extendingvertic'ally lnto said reservoir. The pipe '37, is

removably supported by means of a nipple 37 to which it is connected,said nipple being threaded to engage a threaded openingin'the pad 18.The shaft 13' is provided with a cam 38 located within'the chamber" acondult 35; and provided-with two abutments 39 and '40, positioned toengage the stems .of'a steam valve 41 and of a vent valve 42, saidvalves being normally heldto their seats by suitable springs 43. Thevalve 41 is'located in a valve chamber 14 connectedwith "a steam supplypipe 45. The valve 42 is located within a valve chamber-4c6 commu- 1nicatingwith a pipe 17, open to the atmos- The condensation pipe 26 isconnected in suitable manner, for instance by a T-cou- :pling 48, with asupply pipe 49 and a dis charge pipe 50. The pipe 49 is provided with acheck valve 51 and the pipe 50 is provided with a check valve 52.

In operation the receptacle 19 when empty, occupies the positionillustrated in dotted lines in Fig. 3. The water of condensation flowsthrough the pipe 49 into the branch 26, through the conduit 27 andnipple 29 and the attached pipe 30, into the reservoir 20. hen thereceptacle is in the position illustrated in dotted lines Fig. 3, thecam 38 is inthe position illustrated in. full lines Fig. 4, the ventvalve 421 being. raised and the steam valve '41 seated. Thus as waterflows'into the res ervoir the saidreservoiris vented through V pipe 37,conduit 36, chamber and vent pipe 47. When a sufficient quantity ofwater has accumulated in the reservoir 20 to over-weight thecmmter-baIance 22, :the a receptacle tilts to the position illustratedin full lines iii- Fig. 3. Theefliect of this tilting action is to causethecam 381to shift its position, so that the vent valve-42 is seated andthe steam valve 41 is unseated,

whereupon steam under pressure is admitted from pipe45 to thechamber 35,and passes through the conduit 36 and pipe 37 into the reservoir, abovethe level of the water in the latter. The pressure of the a steam uponthe surface of the Water causes the latter to flow back throughthe-ipipe 3.0 and the conduit 27, to the discharge pipe 50, the pressureclosing the check valve 51 and raising the check valve 52. The pipe 50may, zo fcourse, lead to any desired 10- cality. MTV-hen the reservoir20 is emptied, the counter-weight material will cause the receptacle 19to return to the dotted line position of Fig. 3, whereupon the cam'38will unseat the vent valve 42 and permit the spring 43 to seat the steamvalve 41.

The parts remain in this position until the receptacle is again tiltedbecause "of an accumulation of water in the reservoir 20. It will benoted that the valve;springs 43 in addition to performing-theirfunctions in seating the valves also serve to cushion the receptacle inits rocking movement, through the cam or tappet :38.

In assembling the parts, the elbow 29 is connectedwith thepipe 30, andtogether with the pipe, is inserted through opening .31, being moved toa position where it may be engaged bythe nipple29. As the latter isscrewed home, the elbow is brought firmly against shell of thereceptacle and rigidly supports said pipe 80, Thepipe 87. is coninectedwith "the nipple 37 and inserted through the proper opening in the :pad18, the nipplebeing screwed home as shown in Fig. 5, so as to rigidlysupport the pipe. The pad 18 is then secured to the enlargement 17 insuitable manner for instance, by meansof the bolts 17 It will benotedthat the receptacle and its elements may be assembled as a single unitseparate and independent of the shaft18. By means of this arrangementthe various elements carried by the receptacle maybe removed andreplacedWithout disturbing the shaft or its packing, and repairs may be madewithout necessitating the cutting away of the 'Wall of the receptacle toreach defective parts, as sometimes must be done with apparatus now ingeneral use [It will also be observed that the valves 41v and 42 are ofstandard construction, 2'. 6.,

the valve bodies are attached to straight stems which loosely engage theguide portionsv of the valve easing, whereby said valves may be readllyremoved ,for regrindving and substitution of new ones, byfirst removingthe screwcaps 44?;and TGIIlOWDg' the springs43. a,

It is to be understood that although but one cam .38 is? illustrated ascooperating with but two valves 41 and 42, the invention is not limitedin this particular because the cams and valves maybe duplicated to anynumber desired. Y

From what has been said-itWilLbe readily understood that by means of theinvention,

the-avater of-condensation istrapped ina convenient and efiicientmanner, and that it is automatically disposed of. when aprede- .terminedquantity: has been accumulated, i the operations occurringintermittently and being 'controlledby the weight of' 'the accumulatedwater and itsrelation to theicenter of gravity of the receptacle. a
